No, there is no strong data available that all short-service officers (OTA) do corporate jobs after serving for 10 years in the army. This is for multiple reasons:
1. Some officers prefer to extend their service tenure for four more years, as per army rules.
2. Around 5 percent get a permanent commission, depending on the vacancy.
3. Some other officers prefer to go for other government jobs, such as railways, as there are relaxations and quotas for ex-servicemen in many government jobs.
4. Some prefer to do higher studies, such as an MBA or Ph.D. before starting a new career.
5. Some other SSC officers choose to guide defense aspirants to achieve their goals. Therefore, not all SSC officers choose to take this path to start a new career after retirement.

The Union Public Service Commission UPSC administers the Combined Defence Services CDS exam. I assume you want to compare the Civil Service and CDS. Both are reputed government jobs but are unique in the nature of work. Here is a brief comparison given between the two services:
Civil Services:
1. It includes services such as IAS IPS, and IFS. These are responsible for policy making and implementation.
2. Civil servants maintain public law and order. These services are comparatively less adventurous than CDS.
3. It is mostly a non-uniformed service except for IPS and IRS (C&CE).
4. Civil servants mostly deal with civilians and therefore live close to civilian areas.
5. Civil servants do not have perks such as a canteen, but their salary is usually on par with other group A services. CDS:
1. The CDS exam is generally conducted for defence roles in the Indian Army, Airforce, and Navy.
2. It deals with Indian security and therefore is more adventurous. It can directly expose you to the frontline.
3. The CDS is a well-known uniformed service.
4. CDS does not involve much civilian exposure and officers mostly stay in cantonment areas.
5. CDS officers have additional perks, like canteen service. Therefore, both services are good, and it depends on your aptitude to choose which one you want to choose. If you want an adventurous life that directly involves protecting the country, join the CDS. But if you want to work in the service of people, join the civil service, such as the IAS.
